If a nai scintillator yields 5000 scintillation photons on average for a single 140 kev gamma ray absorbed via photoelectric effect, approximately how many scintillation photons will be emitted for the imaging photopeaks of in-111 (171 kev and 245 kev)? why is the difference in the number of scintillation photons per energy important?
